Too many to mention. The most infamous being Champions of Norrath. By myself I could probably beat it but its more fun with friends (even though they have devolved to cheating which is ok for a few things). The problem is that they hold a very low attention span and keep on changing their characters every time we start it up. I am the only one with a high level powerful character.
Here is a list of all the other games I have not completed due to my shifting attention:
Age of Empires
KOTOR
Dragon Age
Icewind Dale
Final Fantasy XII
Doom 64
Hexin 3D
Demons Souls
Fallout 3
Half-Life 2 Episode 2
Prince of Persia
Oblivion
Morrowind
Marvel Ultimate Alliance 1 and 2
and many more
Games I have completed:
Legend of Zelda OoT, and TP
Portal
Half-Life 2 , and episode 1
Shadow of the Colossus
Fable 1 and 2
Resident Evil 5
Warcraft III, Starcraft, Starcraft BW, Starcraft II
Soul Caliber IV
The lists are actually bigger but these are the ones I can name off easily (and with at least some recognision).
